Batman has developed so much through the years. If we tried to make him one definite type based on an amalgamation of the comics and all movies (the TV series doesn't count in my world

), it would be bordering on impossible. He
should be some type of NT I guess, but that isn't always the case, depending on comic era/movie (yes, I read Batman comics and the graphic novels since I was 14, geek-alert). That's why I didn't cast a vote.
What I can't see however is Nolan's Batman being any type of SP. He is either INFJ or INTJ. Just my opinion of course.
He has and uses Se, but it is weak to start with, and he needs to develop it. I think especially Batman Begins is symptomatic for that. I'll spare you the quotes and situations, just watch it again...
At the end of the day, that's what Batman was always about: A human being who has
developed himself to the peak of his mental and physical abilities. The fact that he uses Se (or any other function for that matter) doesn't necessarily mean it's naturally strong. In Nolan's films, it actually trips him too often. That's a guy who has
learned to use Se to a decent level, but who has still very weak moments (in all three films).
What I definitely see in him is Ni dominance. I mean, how can the end of "The Dark Knight" not reek of Ni? I guess you could build a case for both Ni/Fe or Ni/Te though, depending on your own angle (and fall victim to the Forer effect

).
Nolan's Bruce Wayne is a slightly stronger Feeler than Thinker in my books, but that could well be a means to make the audience feel sympathy. We are talking about a fictional character here after all. I also feel he has other strong Te and Ti users do much of that work for him, and he just adopts it. And yes, I always approach it from looking at Bruce Wayne. I'm not of the "Batman is the real character"-breed, so if you are, you need to look at it differently.
Nolan's Bruce Wayne is humanitarian to his core. He is value-driven (not conceptual/abstract, which would be more Te). That's more Ni/Fe.
Especially the end of "The Dark Knight Rises" could be regarded more Ni/Te: Conflict solved, everything's brought to a conclusion, time to move on.
But, and that's a big one: If you look at it from a Jungian perspective, INFJ and INTJ are more or less the same type. Their dominant function works regardless of their auxiliary. A Ni dom obviously doesn't lead with Fe or Te, so the differences can be really small to non-apparent. Some researchers actually recommend looking at the tertiary or inferior instead, because they are usually more apparent in stressful situations. Weak S in both, doesn't help. The tertiary often works in tandem with the dominant, or even mimics it. T or F - more interesting. Make of that what you will
